@labwreck On pg 114 of the PHB, under wizard abilities, it states a wizard has a spellbook. Would that mean it is free then? A wizard's spellbook is free—it's on the class's list of starting equipment—unless you buy the wizard's equipment à la carte.

@labwreck so if you opt for the starting gold, you have to pay the 50 gold for the book? Yes, if you opt for starting gold, your character doesn't get any of the free equipment listed for his or her class.
